GfS asked.. " if the whole of the scientific endeavor proves God, would you listen??."

Ya' know... what would impress ME is something like the clouds rolling around and forming a giant set of features "made them in His image", and voice from the sky saying in all languages at once: "Hey! Pay attention! Here's how I expect you all to behave!"... then clear consequences if they didn't.
I know that theology 'explains' why that never happens..(free will and all that- 'It don't count if you are forced')... but lacking unmistakable evidence, it's hard to just nod when human theologians TELL you how THEY see it.
